Satellite data on night lights for Africa and Ghana: We use satellite data on night lights in 2010 as a proxy for
local economic development (NGDC, 2015). We use the radiance calibrated version of this
data, to avoid issues related to top-coding. This data records levels of luminosity beyond
the normal digital number upper bound of 63. For each cell, we calculate the mean digital
of the pixels that fell within the cell.

Using QGIS Zonal statistics tool, we calculated the mean of the pixel that fell within the grids.

Input files
1) grid_africa.shp (contains the grid for Africa)
2) ghana_grid.shp (contains the grid for Ghana)
